San Francisco cat - city cat, obviously a wild cat, hunter cat, watching birds fly by but when he can't get them stalks food that is still and dry.

Sink cat - like Thunder Paws, who so adored the sink.

As it happens, my daughter is in San Francisco today, having ventured all the way there from her classes in Fairbanks, Alaska, just to see a concert, a band called Morrisey.

When she calls, I will tell her about Yolo, and suggest she keep her eyes open, just in case he should show up and wind up on the stage, caterwailing with Morrisey.

Now, that would be a concert worth traveling for! Yolo and Morrisey.
